Looking for the factory mattress used in the lower level double bunk in the Grey wolf 26bh with color schedme crimson gold. Ours contains a small hole from a critter, which we didn't notice at time of purchase.

A quick & simple fix is to buy a foam mattress from Sam's club and using an electic knife cut it to fit.
We bought a standard 8" queen and it works like a charm. Alot less expensive than "RV" mattresses.
